Note 2

Note1: VL=27V, IL=320mA (Backlight circuit:9series connection, 3 parallel connection), the ambient temperature is 25℃

Note 2: The “LED life time” is defined as the module brightness decrease to 50% original brightness at Ta=25℃ and 1/2 rated current. The LED lifetime could be decreased if operating IL is larger than 320 mA.
